Peripheral Arterial Disease in Older Adults

A mixed methods study of perceived barriers to physical activity, geriatric syndromes, and physical activity levels among older adults with peripheral artery disease and diabetes

Previous studies suggest a myriad of factors prevent individuals from engaging in physical activity; however, less is known about barriers faced by individuals with multiple chronic conditions, such as peripheral artery disease (PAD) and type 2 diabetes, and how these barriers may impact engagement in physical activity. To date, there are no studies that integrate simultaneous assessment of perceived barriers to physical activity and engagement in physical activity in older adults with PAD and diabetes. This integration is key to understanding the implications of barriers to physical activity and to developing strategies to address those barriers. Therefore, this study investigated the unique physical activity experiences of older adults with PAD and diabetes. This study used a concurrent mixed methods design. Ten adults aged 65 years and older with PAD and diabetes completed semistructured interviews about experiences with physical activity, self-reported questionnaires assessing quality of life and fear of falling, and measures of physical function (eg, 6-minute walk test, chair stand, gait speed). Physical activity was measured objectively with accelerometry. Inductive content analysis was used to identify themes, and integrated analysis was performed to evaluate patterns among qualitative and quantitative variables. On average, participants were 74 years old and spent 10% of their time in moderate or vigorous physical activity (range: 3%-18%); 80% of participants were men. Barriers to physical activity identified through qualitative interviews included lack of accessibility, lack of enjoyment of activity, lack of motivation, and pain and physical health. Facilitators to physical activity were social support, accessibility and convenience, and enjoyment of the activity. Participants with more sedentary time and less moderate or vigorous physical activity tended to report greater fear of falling and greater barriers to physical activity and achieved lower distances in 6-minute walk tests. This research provides insight into both the nature of perceived barriers to physical activity and engagement in physical activity among older adults with PAD and diabetes. The integration of self-reported measures and objective measures facilitates our understanding of the lived experiences of individuals with these conditions. Study findings can be used to support further investigation into factors that influence engagement in physical activity in individuals with PAD and diabetes and to assist in the development of strategies to address identified barriers.

Experiences of living with intermittent claudication

Intermittent claudication is a symptom caused by peripheral arterial disease (PAD) and is associated with pain, impaired mobility and loss of control. Walking ability is reduced due to the pain, and both physical and social functions are often negatively affected, which may lead to patients feeling they are a burden to others. An interview study using a qualitative descriptive design to describe experiences of living with intermittent claudication caused by PAD was carried out during Winter and Spring 2009/2010. Fifteen people suffering from intermittent claudication were interviewed, and the interviews were analyzed using qualitative thematic analysis. Intermittent claudication greatly affects daily living. Six themes were identified: "Experiencing discomfort in the legs," "Moving around in a new way," "Feeling inconvenient when forced to stop," "Missing previous life," "Incorporating intermittent claudication in daily life," and "To lead a strenuous life." The main theme was "Adjusting to a restricted life." The findings show that intermittent claudication has a major impact on daily life. Apart from the severity of symptoms, how the illness is experienced differs among patients, depending on how active the ill person is or wants to be. These findings suggest that increased knowledge about living with intermittent claudication is important to understand the effects on the ill person's life, as a complement to physical examinations when planning individual treatment.

Ankle brachial index measurement in primary care setting: how long does it take?

BACKGROUND

Peripheral arterial disease (PAD) affects over 8 million people in the United States and has been found to be associated with an increased incidence of coronary and carotid artery disease. The ankle brachial index (ABI) measurement is a highly specific noninvasive screening and diagnostic test for PAD, but is rarely performed in primary care office settings. This study sought to determine the actual performance time involved in completing an ABI in a primary care office.

METHODS

Data were collected by one provider on a convenience sample of women who met the inclusion criteria. The time was recorded at the beginning and upon the completion of the ABI procedure for each patient. Analysis of the time data was completed and barriers to performing the ABI were recorded by the provider.

RESULTS

The average time to complete an ABI was 5 minutes, with a range of 3-11 minutes. In 83.8% of patient encounters, the ABI procedure took less than 6 minutes to complete. Barriers identified by the provider included the additional time needed to explain the test and assist patients into the proper testing position.

CONCLUSIONS

The actual performance time for an ABI in a primary care setting takes an average of 5 minutes, but additional time may be required for patient preparation and education. With proper scheduling and training, the ABI can be completed in a timely manner. The ABI is an important screening/diagnostic test that can be performed in primary care and potentially impact patient treatment plans.
